ABSTRACT:
A lightweight mechanical structure is provided for supporting an RF partitioning network for a large dimension array antenna. The network consists of two horizontally disposed stripline RF dividing circuits positioned in two enclosed portions of the network. The network is formed within an enclosure which is made up of rigid side frames and electrically conductive ground planes between which the microwave stripline dividing circuit is formed. The ground plates of the stripline circuit are bonded to rigid honeycomb materials so as to provide structural support. The network is assembled by means of suitable structural adhesives. The structure of the partitioning network of the present invention provides for the RF feeding and mechanical support of large dimension array antennae in one assembly. The network requires a reduced number of tooling and finishing steps so as to achieve a low manufacturing cost while still providing good planarity and rigidity properties and reduced weight in a structure having large overall dimensions.
